tubasync · tapper

the beat you hear, in your hands. two tones, one per ear, a glide between offsets, and a bilateral tapper that keeps time with the beat.

presets tuned for coin motors

each one keeps the tap rate still, so the motors never chase a moving target. pick one, then start.

intensity, buzz length and shape live on the device knob (hold to switch setting, turn to change). this page sets the speed and turns taps on and off; the knob can too, and whoever acted last wins.
